To evaluate the effect of egg age of Spartocera dentiventris (Berg) on the parasitism by Gryon gallardoi (Brethes), groups of 12 eggs of 2, 3, 4, 5, 6, 7, 8, and 12 days old were exposed to one female of G. gallardoi on a test tube, with the wasp observed for 2h subsequently. Later, the eggs were individualised and incubated (25 +/- 1 degrees C; 12h photoperiod) until adult emergence. To identi...

The efficacy of a photostable formulation of methoprene and two photostable juvenoids, fenoxycarb and pyriproxyfen, and their residual activity in inhibiting the emergence of adult cat fleas, Ctenocephalides felis (Bouché), was studied in topsoil. Nursery pots composed of clay, peat, and plastic, and wooden flats were used to hold soil samples. Treated soil samples were exposed to sunlight duri...

We tested the effects of three vegetation management strategies for constructed treatmentwetlands on adult shore-ßy (Diptera: Ephydridae) successional occurrence and emergence in southern California. Before ßooding with efßuent from a nearby wastewater treatment plant, eight 0.1-ha research cells were randomly assigned to (1) control cells which were burned to reduce the abovegroundplantbiomass...

The present study records the first successful colonization of Mansonia annulata and describes colony maintenance with modification of rearing medium and host plants. Three species of Mansonia mosquitoes (Ma. uniformis, Ma. indiana and Ma annulifera) were successfully reared in ambient environments with adult emergence rates > 50%, while Ma. bonneae and Ma. dives yielded emergence rates > 30%. ...

The effects of topography, soil moisture, wind and grazing on the emergence and survival of seedlings of Festuca spp. were examined in the steppe zone of Patagonia, Argentina. Ungrazed and grazed field treatment plots were established on a plain and a north-facing slope at the Media Luna Ranch (43" 36' S, 71" 25' W). On the leeward and windward sides of each of 15 Festuca plants, 0.1 m x 0.4 m ...

This 15-year longitudinal study examined the stability of attachment representations from infancy to adolescence and investigated the emergence of unresolved representations during adolescence in a sample of 47 16-year-olds. Attachment was assessed at 12 months using the Strange Situation Procedure, at 4 years using the modified Strange Situation Procedure, and again at 16 years with the Adult ...
